The ranking of institutions is determined by aggregating the D-indexes (Discipline H-index) of all affiliated scholars, whose principal area of publication is Biology and Biochemistry, at each institution. The D-index is a discipline-specific variant of the H-index that exclusively regards publications and citations in Biology and Biochemistry, ensuring a focused and accurate assessment of performance in the specified domain.
Scope of Research Considered
The Research.com ranking is built on an expansive analysis of bibliometric profiles. In this edition, a total of 279,971 scientist profiles were systematically screened from an array of bibliometric sources. Out of these, 97,416 scientists who specialize in Biology and Biochemistry were subjected to in-depth evaluation.
Inclusion in the ranking required that scientists meet a minimum D-index threshold of 40, with the majority of their high-level publications classified within Biology and Biochemistry. Recognizing excellence, a researcher’s professional awards and field-specific achievements were also integral to qualification. To ensure the consistent representation of the upper echelon of the scientific community, the D-index threshold for top researchers increased in increments of 10, dynamically adjusted to the estimated population size of each discipline. This ensures that the top 1% of scholars are faithfully incorporated into the ranking list.
A further quality safeguard mandates a proximity of 30% or less between a scientist's general H-index and their D-index, reinforcing the requirement that a prominent share of their scholarly impact belongs to Biology and Biochemistry. Additionally, laudable achievements and recognition in the field further inform the assessment process.
Verification and Additional Evaluation Practices
Recognizing the inherent limitations of relying solely on raw data, Research.com implements meticulous verification procedures to augment the accuracy and credibility of its rankings. Every scientist profile was manually verified and cross-checked against publications indexed across a wide spectrum of reputable sources.
While the number of papers published in high-impact journals and conference proceedings is not directly factored into the ranking position, it serves as a valuable supplementary indicator of a scientist’s contributions to the field. The definitive ranking positions are derived from each researcher’s H-index, calculated from records in OpenAlex and CrossRef—the most established and widely-used bibliometric databases within the academic community.
